At least a good share more would be alive to speak it.
Catholics saved Europe from Islam. Not the Jews. Not the Albigensians. And not the Protestants.
Exactly. NO ONE saved the Jews, Cathars, Poor Men, Waldenses... etcetera, etcetera, etcetera, ad-infinitum and particularly, ad-nauseum...
ONE-THOUSAND, TWO-HUNDRED, and SIXTY YEARS of it. That's far more than enough to cancel out any "good" performed in "saving" Europe.
Ahem, there were no Protestants then. Crusades were much earlier than Protestantism I think.
